T 0 all "whom it may concern.

Be it known that we, HEINRICH Gonnnnne, manufacturer, a subjectof the King of Prussia, residing at 135 Rosstrasse, Crefeld, Rhineland, in the Kingdom of Prussia, German Empire, and FRITZ Lnnwrcs, workmaster, a subject of the King of Prussia, residing at 58 Uerdingerstrasse, Crefeld-Bockum, in the Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in Equalizing Devices for Silk Fabrics, of which the following is a specification.

This invention relates to an improved device for equalizing silk fabrics, a so-called scouring device, the equalizing effect being attained on account of the scouring or rubhing action produced on the silk fabric while the latter is drawn over a stationary lmife fastened to the breast beam of a loom.

Devices for equalizing webs have been known for a long time. From these the objects of the present invention differs with regard to the manner in which it is arranged on the loom, as well as in its particu lar construction. While equalizing devices as used hitherto were not directly connected to the loom and required, in many cases, special machinery to operate them, the equalizing device according to the present invention is fixed to the breast beam of the loom.

The device consists of a knife that will be described more particularly below, over the edge of which knife the web to be equalized is drawn. l/Vhile before treatment the web on examination in incident light appeared thin and transparent, it has become more tight, more equal and, as regards quality more valuable after treatment.

In the annexed drawings an embodiment of this invention is given as an example.

Figure 1 is a front elevation of the device in which Z) represents the longitudinally divided metal bar between the parts of which the knife (4 is adjustahly held by means of the slidable collars c. Fig. 2 is a sectional view on the line A-B of Fig. 1. Fig. 3 is a plan view of the knife. Fig. 4- is a side view of part of a loom provided with the equalizing device, and Fig. a plan thereof.

The device consists mainly of a knife a held between two semi-circular metal bars Z), which are mounted in brackets A, secured to the breast beam B of the loom and extend ing rearwardly therefrom. These two bars are kept together by means of two adjustable collars 0 which are held in place on the bars by set screws (Z. The knife a consists of a metal plate with a cutting edge f on one side. To prevent damaging the lists of the fabric the cutting edge of the knife is, toward its ends, provided with two indentations g. Thus only that portion of the knife edge extending between these two indentations is used for securing the fabric. ()n drawing the fabric over the knife the lists of the fabric come in place over the roundoff corners h of the knife edge, which arran 'einent prevents damaging the lists.

According to the width of the fabric to be equalized a knife of corresponding length is applied which knife may be easily detached from the device, and substituted, by loosening and sliding the adjustable collars and bringing them again into position over the newly inserted knife.

Having thus des .ribed our i vention what we claim, and desire to secure by Letters Patent, is-

1. in a loom, an equalizing device for silk fabrics and especially for ribbons, comprising a stationary knife suitably supported in the rear of the breast beam. the fabric to be equalized being adapted to be drawn over the edge said knife while under treatment. substantially as set forth.

2. In a loom, an equalizing device comprising a pair semi-circular metal bars, a stationary knife supported thereby in the rear of the breast beam, the cutting edge of said knife projecting slightly above the bars, said bars being pressed together by means of slidably mounted collars and set screws, substantially as described.

3. In a loom, an equalizing device comprising a pair of semi-circular bars, an interposed stationary knife supported thereby tact With-the lists of the fabric, substantielly the rear of the breast beam, collars as described.
